Chapter 26, Problem 49DSP

Interpretation Introduction

Interpretation:

The carbon atom of L-glutamic acid, which is involved in the only carbon-carbon bond forming step of the synthesis given, is to be determined.

Concept introduction:

Natural L-glutamic acid has S configuration. If no reaction takes places at the chiral carbon atom of the amino acid, then its configuration is retained in the products formed.

The alpha carbon atom in the amino acid is attached to a nitrogen atom, the carboxyl carbon, and one other carbon atom.

Tracing the carbon atoms of the amino acid in the product, the carbon atoms of the amino acid in the product can be identified.
